No. Should I create it?

If there isn't one already that's fine. Could you please explain the use case for this feature?

Yes of course. I needed to show the column name of the picker.

So I added the "showName" property in the 'PickerColumn' interface. If it is set to true, the column name is shown on the top of the column.

I also added an example in the test script.

Thanks for the clarification and apologies for the delay. What is the benefit of showing the column name instead of using prefix or suffix? In practice, the prefix and suffix properties are what describe the columns. Here's an example from the stock iOS clock app:

I think the addition of this API is a bit confusing since it lets you describe the column in two different ways. Here is a screenshot of the example you added:

The "hours" suffix describes the column, so having showName here is redundant in my opinion.

Thanks for the PR! I discussed this with the team and we are unable to accept your PR at this time. We feel that the existing suffix and prefix properties already provide the functionality that the proposed showName property would provide.

As I mentioned in #23576 (comment), native iOS apps use the suffix and prefix features to assign labels to picker columns. Adding the showName property to Ionic Framework would allow developers describe a column in two different ways which we feel may lead to a confusing user experience.

In the future we recommend opening an issue first before creating a PR as it lets us discuss the scope of a feature before any programming work begins. Please let me know if you have any questions. Thank you!
